Further, the inner cavity is coaxial with the rubber ring and is annular.

Further, the closer the rubber tube is to the sleeve, the larger the diameter is, which facilitates the rubber tube to hold the cable tightly and enhances the sealing performance.

Further, the extruding device is a threaded pipe, and the outer wall of the casing is provided with threads matching the threaded pipe, and the pressing block is sleeved on the casing, and the pressing block is located between the threaded pipe and the rubber ring ; Easy to fix the position of the pressure plate.

Further, a rotating handle is provided on the outer wall of the threaded pipe; it is convenient for manual adjustment of the threaded pipe.

Further, the inner cavity of the rubber ring is filled with water; the cost is low, and the effect of the rubber ring to seal the pipe is convenient to be enhanced.

Compared with the prior art, the utility model has the advantages that: in the utility model, the rubber ring is extruded by the pressing block and the casing, so that the rubber ring diffuses in the circumferential direction, thereby filling the gap between the casing and the cable duct, and passing through The rubber tube can seal the casing and the cable; the sealing effect is good, and it is easy to disassemble and assemble, and the axial movement of the cable due to thermal expansion and contraction or other reasons will not affect the sealing.

Description of drawings

Below in conjunction with accompanying drawing, the utility model is further described:

Fig. 1 is the structural representation of the utility model before rubber ring compression;

Fig. 2 is a schematic structural view of the utility model after the rubber ring is compressed.

detailed description

Referring to Fig. 1 and Fig. 2, a pipe hole sealing device for a cable duct, including a casing 1, a rubber ring 2, a stopper 3, a pressing block 4, an extrusion device for pushing the pressing block 4, and 1 set of casing Connected to the cable, the stopper 3 is fixedly connected to one end of the sleeve 1, the pressure block 4 is arranged on the sleeve 1 and can move along the axial direction of the sleeve 1, and the rubber ring 2 is sleeved on the sleeve 1, the rubber ring 2 is located between the block 3 and the pressure block 4, the rubber ring 2 is provided with a closed inner cavity, the inner cavity is coaxial with the rubber ring 2 and is annular, and the inner cavity of the rubber ring 2 is filled with Fluid; one end of the sleeve 1 is connected with a rubber tube 5, and the stopper 3 and the rubber tube 5 are respectively located at both ends of the sleeve 1. The closer the rubber tube 5 is to the casing 1, the larger its diameter is. The extruding device is a threaded pipe 6, and the outer wall of the casing 1 is provided with threads matching the threaded pipe 6, and the pressing block 4 is sleeved on the casing 1, and the pressing block 4 is located on the threaded pipe 6. Between the rubber ring 2. A rotary handle 7 is provided on the outer wall of the threaded pipe 6 . The inner cavity of the rubber ring 2 is filled with water, air or other fluids.

When in use, turn the rubber tube 5 onto the sleeve 1, make the cable pass through the sleeve 1, then insert the sleeve 1 into the cable duct, and make the threaded tube 6 approach the stopper 3 gradually by rotating the handle 7, so that the rubber The ring is compressed twice, and then the rubber ring 2 is squeezed to fill the gap between the sleeve 1 and the cable duct, and then the rubber tube 5 is turned down so that the rubber tube 5 is sleeved on the cable.

In the utility model, the rubber ring is extruded by the pressing block and the casing, so that the rubber ring diffuses in the circumferential direction so as to fill the gap between the casing and the cable duct, and the casing and the cable can be sealed through the rubber tube; the sealing effect is good , easy to disassemble, and the axial movement of the cable due to thermal expansion and contraction or other reasons has no effect on the seal.
